‘Discover Milwaukee—Relocation Guide’ describes Lake Country: “Northwestern Waukesha County is known as "Lake Country" because of the dozens of sparkling lakes that were carved out by glaciers 15,000 years ago. This has long been a summer getaway for well-heeled Chicago and Milwaukee residents, but the area's scenic beauty has made it a popular location for year-round homes as well. This area offers a variety of boating and fishing opportunities, including Pewaukee Lake, the largest inland lake in the county.

Listed in Lake Country is: Oconomowoc • Pewaukee • Hartland • Merton • Delafield • Summit • Dousman • Chenequa • Nashotah • Oconomowoc Lake • Lac La Belle. Bright blue lakes and rolling hills punctuate this popular area in northwestern Waukesha County. Boating and fishing are popular here. This is an area filled with natural wonders, most of them created by glaciers thousands of years ago. Lapham Peak, located in the Kettle Moraine State Forest near Delafield, is the highest point in the county with an elevation of 1,233 feet above sea level. It is also one of the hottest development areas in southeastern Wisconsin, with many new upscale homes and subdivisions, especially near Oconomowoc and Delafield.”
